It's quite a while, that I wrote about the iDo S600 Pocket PC Phone Edition from Taiwanese manufacture Kimpo and in the meantime, Kimpo already released the iDo S601 (which I have totally overseen and which is even not announced on Kimpo's website). The iDo S601 is the last Pocket PC Phone Edition Kinpo, not very well known in European or the U.S. but guys from the newly launched iDo User Forum just got their hands on an iDo S601 and wrote a review (PDF File). Compared to S600, the S601 uses the latest Windows Mobile 5 operating system (contrary to the S600 which was using Windows Mobile 2003 only) and supports in addition to GSM and GPRS Wi-Fi.

The iDo S601 costs around 450 Euro and is already on sale. If you own one already, the new iDo User Forum might be a good place for you to start; if you are looking for something completely different the iDo S601 might be something interesting for you.
